In 1999, QEI became ISO 9001:2008 Certified. ISO 9001:2008 specifies requirements for a quality management system where an organization needs to demonstrate its ability to consistently provide products that meets customer and applicable statutory and regulatory requirements and also aims to enhance customer satisfaction through the effective application of the system, including processes for continual improvement of the system and the assurance of conformity to customer and applicable statutory and regulatory requirements. This certification is another way we demonstrate to our customers the level of quality we demand of ourselves.
